I posted this as a reply to Kevin, anyone got any answers?

In premiere 5.1 one can select a de-interlaced output. With the LSX encoder one can select to de-interlace the input file.

Trouble with those options seems to be quite a loss in picture quality, infact the LSX encoder asks do you really want to de-interlace the input file yes/no?

I have been using a render out of premiere which is called "no fields" and that seems to a better choice as it provides a higher quality picture but does not get over the problem entirely. No idea what it really does though.

I have a commercial example (720 x 240) of some bike riders passing left to right of the screen at high speed and there is no obvious interlace problem and the image is better than I can produce - how do they do that I wonder?

I have tried single field captures and they solve the interlace problem but at very high speeds the picture jerks - anyone know how to get the problem solved?

I wonder if it gets back to how it was taken? Wonder if fast shutter speeds improve the end result? Anyone know?

"Trixter" recommends the following at http://www.oldskool.org/mpeg/

1.Capture full-frame video (480 lines). 2.De-interlace the video frames. This properly combines the two captured fields into a single frame. 3.Smoothly resize the de-interlaced frames down to your output size, typically 352x240. (The "smooth resize" process is sometimes called "resampling".) 4.Encode the resized frames with a software encoder.

Does this help ?
